[meta-networking][PATCH] dhcp-relay: Pass cross configure flags to bind build

[Khem Raj <raj.khem@gmail.com>]

This ensures that host tools like 'gen' are built for build host and not
target. internal bind build supplies its own options to configuring it,
where it does not pass --host option and as a result it does not deduce
it to be a cross compile and hence these variables are not set property
inside bind build

Fixes
| ./gen: /usr/lib/libc.so.6: version `GLIBC_2.38' not found (required by ./gen)
